| 摘要 |
The invention relates to a method for inspecting transmission channels indicated as occupied in a communications system having peripheral modules for preparing subscriber-side transmission channels. According to the method, a test sequence transmitter (TxTS) carries out a system-side transmission of a test sequence (TS) to a control unit (CU1) for a selected peripheral module (PM 1). The test sequence (TS) is transmitted to a test sequence receiver (RxTS) over a transmission channel (PM1_CH1), which is indicated as occupied and which is assigned to the peripheral module (PM1). The test sequence (TS_T), which is transmitted by the test sequence transmitter (TxTS), and the test sequence (TS_R), which is received by the test sequence receiver (RxTS), are inspected for an evaluation of conformity. In the instance of non-conformity, the selected transmission channel (PM1_CH1 ) is disconnected in a targeted manner.
